摘要

The synthesis of single phase tin-ferrite, SnFe_2O_4, from tin (II) oxide or stannous oxide (SnO), and hematite (α-Fe_2O_3) solid precursors was carried out via high energy ball milling (HEBM) under wet condition involving the addition of controlled amounts of acetone. The stoichiometric amounts of the precursor materials were ball milled continuously for up to 22 h in a Spex-8000D mill using a ball-to-powder ratio of 40:1, with hardened stainless steel balls in WC-lined jars. The time-dependent formation of the SnFe_2O_4 based on combined X-ray diffraction and room temperature Mossbauer spectroscopy (MS) measurements revealed reaction enhancements associated with particles size reduction. The 22 h milled material indicated that synthesized SnFe_2O_4 had a particle size of 10.91 nm, coercivity of 4.44 mT, magnetic saturation/remanent ratio (M_r/M_s) of 0.085, while its superparamagnetic behavior was confirmed based on the combined MS and vibrating sample magnetometer measurements.
